Potential cutting situations I can imagine in a Red Cross Shelter:
1. Opening boxes, MRE's, or other packaging.
2. Making bandages or slings.
3. Cutting food into child-sized peices.
4. Altering clothing.
5. Splicing wires.
6. Poking hole in cap of water bottle to make it spill-proof for child.
7. Cutting rope for makeshift curtains/privacy walls.

A trauma shears could do most of this stuff, but would be tricky for some.
